You can't do that. The point of the "standard" branch is that
it doesn't contain preempt-rt.
So you do need the patches in both places.
preempt-rt changes enough semantics that it can't always be in
place, and we don't guarantee that it can be completely #ifdef'd
out when you turn off the RT configs.
Also, experience shows us, that you will eventually need patches
that are -rt specific, so that's what the branch is for. BSP
patches shouldn't be touching files that -rt touches, so stacking
the BSP branches on two branches is the lesser of all evils.

See above. It's your BSP patches that move, not the -rt.
